MILK-CAN.

Specification of Letters Patent.

Application filed January 13,1919. Serial No. 270,851.

To all whom it may concern:

Be it known that I, AUGUSTINE DAVIS, J r., a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Milkifans, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

An object of my invention is to provide a milk can which shall be adapted for the use of the ordinary push-in and umbrella milk can covers and also for a lock cover. The special object of the invention is to provide a lock cover which can be readily and easily secured over the mouth of the can without the necessity for any locking bands or lugs on the can itself, so that a moresanitary can is provided without projections or shoulders on the can to accumulate dirt. Moreover the cover may be locked without twisting or turning. The cover is also designed to be applied on the mouth of the can so that the cover does not have to, be applied at anyparticular p0int, thus very materially saving wear on the can. A further object is toprovide a can where not only curved surfaces are presented, but which can be welded without seams on the inside.

Still further objects and benefits of the construction will be evident from the following description in which the various ad- "vantages are pointed out'and covered in the claims. I

In the drawings which embody the pre ferred construction of my invention, Figure 1 is a side elevation of my improved can with the cover in place and one side locked.

Fig. 2 is a central vertical section of the same. 1

Fig. 3 is a side elevation of the can, illustrating its adoption for use with the push-' Fig. 8 is a perspective view of the locking arm, with its cam lug.

Fig. 9 is aperspectlve View of the coopcrating 'camdevice which is secured to the Patented Mar. 1, 1921.

The can itself isjmade up of three parts I assembled together and welded either electrically, or by the oxyhydrogen .or oxyacetylene methods.

The bottom of the can 1 is pressed out of a sheet of suitable sheet metal'rounded at the corners, with a slightly upturned flange" upon which is welded'the cylindrical portion 2 of'the can so as to leave a smooth imperceptible joint on the inside, and around the bottom an outside ring '3 is secured,

preferably by spot welds 4 so as to form a substantial support for thecan.

The breast and neck of the can 5 is formed out of single piece of sheet metal, with the lower edge of the exact diameter of the cylindrical portion 2, and this joint is welded as in the case of the bottom, and to strengthen the construction and for holding the handles 7, 7, which are secured there'- to, a band 6 is welded, preferably by spot welds 8 on the outside of the can. The neck kind around the neck of the can on the outside, and it will be obvious that this construction of can will be adapted to receive the ordinary push-incover 10, or the um.- brella cover 11' as indicated in Fig." 3.

'Where' it isnot desired to use the ordignary push-in or umbrella cover, I provide 7 the lock cover 12. This cover'is. formed of substantial sheet metal pressedintoshape, with the depending flange 13 to fit over the neckofthecan' as follows: penings 14,14, are formed on opposite sides of the depending flange and over each of these openings a recessed cam plate 15 is secured, preferably by rivets, in

which are formed with cam surfaces 22 tocorrespond to the cam surfaces18 in the 7 95; For lockin this cover in place, I provide horizontal position with the lever arms projecting upwardly, the cam surfaces will so fit as to allow the studs 19 to project out- 'wardly, bringing the inner surface 23 of The levers 20 are provided withflat por tions 24, so that they can be readily and easily pushed down into horizontal position,'and as mostconvenient for manipulation,- I prefer to provide that these locking levers shall be turned in an opposite direction. A stop lug 25 projects outwardly for the two cam plates 15 on opposite sides of the studs so as to permit movement only in one direction, and'I also provide for-each locking lever a corresponding lug 26. These two lugs are pierced with openings 27, 28, which,when the levers are turned down, are 'roughtinto registry, so that a seal can be secured through these openings. It will be noted that when the levers are turned down over a horizontal position, they come below the top surface of the cover so that there is nothing to interfere with stacking the cans on top of each other, and the camining operation against the outer head around the neck of the can forcesdown the cover so as to give an airtight seal joint for the cover on the can.

Inasmuch as the camming surfaces are on the cover, no lugs or bands are required to secure same to the can, the cover can be dropped into place any point around the neck of the can, and there is no wear by reason of the necessity of always securing the lid at some, definite position, Moreover the lid does. not have to be turned or twisted to locate it in proper position, which takes time and ordinarily requires some shifting of position of the user.

2. In a milk canrprovided with an open mouth andbeaded rim, a cover therefor and a cam lever pivotally and sli'dably mounted in thecover, with cam surfaces intermediate the lever and cover, whereby upon rocking the lever it will be drawn into locking engagement with the rim.

In a milk can provided with an open mouth and beaded rim, a cover therefor and a cam lever pivotally and slidably mounted in the lever, with cam block on the lever and a cam plate on the cover, whereby upon rocking the lever the cam block will be forced under the rim of the can to lock the cover in place.

4. In a milk can provided with an open mouth and beaded rim, a flanged cover for the can adapted to fit down over the rim, with looking levers pivoted in the flange on opposite sides of the cover andinovable inwardly, with means for forcing said levers inwardly to engage the rim and lock the cover in place. I

5. In amilk can provided with an open month and headed rim, aflanged cover for the can adapted to, 1% down over the rim, with locking levers pivoted in the flange on opposite sides of the cover, and movable inwardly, said levers and cover being provided with interengaging cam surfaces, whereby the levers will be forced inwardly upon pivotal movement to lock the cover in place. 6. A milk can provided with an open mouth and externally unobstructed. neck,

and with a reinforced head at the mouth, whereby the can shall be adapted to receive and hold any of the threetypes of covers, the bead being adapted to cooperate with cam blocks pressing upward thereagainst AUGUSTINE Davis, Jr.
